Being able to use pdffiller has been a lifesaver in so many ways: neatness, conversion of files, time saver, etc. I am a high school English teacher, and I also raise miniature Australian shepherds and quarter horses; with pdffiller, filling out forms online and being able to save them and/or fax them has saved me time, given a more professional look to my papers, and actually improved my productivity in different areas of my work.
The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?
What do you like best?
I like how easy it is to create forms and to fill out PDF forms. I also like the mobile app.
What do you dislike?
It's a bit slow, and sometimes crashes, requiring you to start over
Recommendations to others considering the product:
Definitely get and use the mobile app
What problems are you solving with the product? What benefits have you realized?
It makes it very easy to fill in forms that clients send me.

Love the app!
Overall I really like the app and it has been quite useful for me as a realtor =)
Great way to fill out forms and make your own fillable master form.
I have had a hard time figuring out how to easily share and send the form you want and the notifications when you receive it back. Wish I could save the docket in my own files
Easy to Use
It's kind of a time saver in the end with not have to use the typewriter or hand write them, would be easier though if you didn't have type each form, if they are the same it should copy the data onto each one.
I liked that I didn't have to pull out (yes it's a dinosaur) typewriter to fill out my 1099's every year any more once I found this program online. I can also use it for other forms as well.
I don't like that you have to retype each 1099 for each copy of the form, it should carry them forward to each copy and you just review them for differences.

Excellent, easy to use and saves a lot of time
It has saved me time mainly and a lot of hassles in getting physical signatures.
I have signed and shared documents within minutes rather than signing/scanning or mailing.
If you want to save time and get your documents signed ASAP, PDFfiller is a must have software. You can use it anywhere as long as you're online and you can edit it too without any hassles. It's very affordable.
